For a long time the cooling in my house was just sub par.
I would turn down the thermostat and nothing would happen.
I changed the air filter, cleaned the inside of the cooling system and hoped for cold air. The most I would get is tepid to cool air blowing around the house. That was the issue, the actual air coming out of the vents was not cold enough. I did a lot of googling about the problem. All that did was scare me though. I thought I might have a damper issue, wiring concern or need a brand new cooling system. Thankfully I took a few days and just thought about what could be going wrong. Rather than jump on the horn and have an air conditioning business come over, I used my brain. I started looking over my outdoor air compressor and I realized that it was at an angle. It was not totally on its side, just slightly off centered. I then looked up if that could affect the indoor air handler cooling. Yes, when an outdoor unit is tilted, all the coolant pushes to one side of the machine. Then when the AC operates, no coolant is going over the air. So you then get tepid air inside of the home. All I needed to do was get a few cement blocks to level my AC machine out. It was almost immediate where I had cold air once again. Thankfully I did not have an AC business come in and fix this small issue. I figured it out on my own.
